A coronial inquiry into last years Bronzewing mining
tragedy in the Goldfields region of Western Australia has concluded
that Normandy Mining, the owner of the Bronzewing gold mine, was
not to blame. Three service crew workers, Troy Woodard,
Timothy Bell and Shane Bell, died on June 26 last year after 18,000
cubic metres of rock and sludge buried them 400 metres underground.
A fill barricade on level 12 collapsed, flooding the lower levels.
A postmortem confirmed that the three miners died of asphyxiation.
Coroner Alastair Hope acknowledged extensive safety problems,
but issued a contradictory verdict excusing Normandy. I
find that Normandy caused or contributed to the deaths in the
sense that Normandy was responsible for the placement of fill
and Normandy was responsible for the construction of the barricade
wall. In making this finding I should not be taken as attributing
blame to Normandy.
Evidence given at the inquest cast doubt on the mines
safety, particularly the maintenance and condition of the level
12 barricade. Four days before the wall gave way, Paul Harrison,
a backfill technician spotted a crack in it, and pressure readings
were higher than the safety limit of 200kPa (kilopascals). Harrison
also found backfill pouring out at the level 11 wall. Harrison
radioed his supervisor about his findings.
Two hours before the collapse, another backfill technician,
Justin Jackson, reported swinging pressure readings at the level
12 wall. Worried about the readings, he radioed his boss Michael
Fasanini.
During the inquest, Fasanini denied being contacted, but this
is at odds with a statement made by Normandy executive Paul Dowd
two days after the tragedy. According to the Melbourne Age,
Dowd said the wall was equipped with standard monitoring devices
that were checked an hour before the wall collapsed. His comments
suggest that management must have known what Jackson had found.
Jackson testified that another mine manager had instructed
him not to bother checking for pondinga visible
build-up of water behind the barricadebecause it was not
important.
Other problems included a broken drain at the base of the wall
that contributed to water accumulation and pressure on the wall.
Conveniently, Normandy mine managers Scott Atkinson and Rod
Young stated that if only middle management had informed them
of the safety concerns, they would have evacuated the mine site.
Months before the incident, Normandy had commissioned a report
on the ramifications of a barricade collapse. It warned that a
collapse would be catastrophic, possibly causing multiple fatalities.
In the weeks before the accident, a breakdown had occurred
in the regular weekly sampling process. As a result, laboratory
samples were e-mailed late to Normandy on the day of the collapse.
The results showed that the backfill contained a dangerously high
level of tiny particles that could clog up water flows, creating
ponds and putting added pressure on the wall.
Atkinson, the underground mine manager, admitted that he knew
about the laboratory sampling breakdown but claimed there was
no reason to believe the results would be different from the previous
months.
Mine workers also testified that, in the weeks before the collapse,
the barricades were frequently at or above the pressure level
(200kPa) at which they were not supposed to approach the wall
at all. Yet management told them to continue taking readings at
the walls face.
In a report handed to the inquest, Melbourne Universitys
Civil Engineering Department stated that the barricade could take
only a pressure of 200kPa. At that pressure microscopic cracks
would have formed, lowering the ultimate level of pressure that
the wall could withstand.
The company baldly denied this at the inquest, asserting that
the wall could take 500kPa. But the company did not explain why
workers had been instructed not to go near the wall at 200kPa.
Nor did Normandy explain why it had to cobble together an emergency
crew from all over the state after the accident. The media reported
the companys efforts as a heroic struggle against
time yet Normandy had just sacked the majority of the previous
emergency crew for cost-cutting reasons.
Safety recommendations
Coroner Hope issued a series of recommendations, including
ensuring that miners could check for ponding, that
operations were to stop if backfilling could not be monitored
properly and that barricades be of adequate strength with proper
water drainage. Safety recommendations have been made before,
however, and nothing has been done.
Normandy received sharp criticism from the widows of the three
miners during the inquest. Timothy Bells widow, Ms Shimmon,
stated: To me the incompetence of management has become
clear. I think that policies and procedures need to be put in
place and they need to be enforced.
Australian Workers Union (AWU) officials said that they would
be taking up safety issues with the Department of Minerals and
Energy (DME), yet AWU officials sit on the DMEs board of
advisers, alongside Normandy and other mining company executives,
effectively incorporating the union into the running of the mining
industry.
West Australian trade union council leader Tony Cooke declared
that managers should be charged with industrial manslaughter,
arguing that these penalties should be in place against
the worst cases of employer neglect of their duties under relevant
health and safety laws.
But clearly, given the law, Normandy and many other mining
companies have successfully avoided responsibility. The DMEs
prosecution of Normandy under the Mines Safety and Inspection
Act has been adjourned until September, and the coronial findings
could help the company escape liability, or lessen the chance
of even the small maximum fine$100,000being imposed.
Since taking office early this year, the state Labor government
has backed away from Premier Geoff Gallops earlier view
that employers who fail to provide a safe working environment
should be jailed. While still in power, former premier Richard
Court professed deep concern over the Bronzewing deaths, visiting
the mine during the rescue operation. Nevertheless, nothing has
improved.
Five more West Australian workers have died in mine accidents
since the Bronzewing tragedy. At Bronzewing itself, another 18
miners suffered serious injuries during 2000. On the day the coroner
handed down his findings, nine miners were trapped in a rock fall
at Strzelecki underground gold mine in the Goldfields region.
As the sacking of emergency crew members indicates, Normandy,
which had taken over the Bronzewing mine a few months before the
incident, was in the process of restructuring its operations to
slash costs and drive up profit levels. It has since reported
production increases. The coronial findings give it a green light
to continue doing so at the expense of workers safety.
